2.1About AIS
The marine Automatic Identification System (AIS) is a location and vessel
information reporting system. It allows vessels equipped with AIS to
automatically and dynamically share and regularly update their position,
speed, course and other information such as vessel identity with similarly
equipped vessels. Position is derived from GLONASS or GPS and
communication between vessels is by VHF digital transmissions.

the radar beam path and mounted
on a rigid surface.
Radar beam path
GNSS Antenna
5m (16ft)
● The GNSS antenna should be located where it has a clear,
unobstructed view of the sky overhead.
● The GNSS antenna should be mounted as high as possible, however
it is not recommended to mount the antenna on the top of a high mast
where the motion of the vessel will cause the antenna to move and
potentially reduce the accuracy of the GNSS position.
● Route the GNSS antenna cable to the AIS transceiver. If extension
cables are required all junctions should be made using appropriate
co-axial connectors and made watertight.

4.6.8Messages
AIS text messages and Safety Related Messages (SRMs) can be received
from other AIS equipped vessels and also sent to specific vessels (addressed
messages) or sent to all vessels in range (broadcast messages).
Reception of an AIS text message is indicated by the presence of the message
icon at the top of the screen. This icon is shown whenever there are unread
AIS text messages. Messages can be reviewed and replied to via the Inbox.
The AIS transceiver can store up to a maximum of 20 messages in the Inbox
and 20 messages in the Sent folder. If the number of messages exceeds 20
then the oldest message will be overwritten.
When a Safety Related Message is received the user will be notified
immediately with a pop-up showing the message. Standard text messages are
not displayed on receipt, however the message icon will be displayed at the
top of the screen.
This alarm occurs if the difference in position
reported by the internal and external GNSS
receivers is too large. Check the vessel
dimensions and GNSS antenna locations
have been entered correctly.
the course over ground and heading data is
greater than 45° for more than 5 minutes.
This alarm only occurs if the vessel speed
over ground is greater than 5 knots.

AIS messages can be viewed, created and transmitted from the ‘Messages’
menu.
The available options are:
Compose - takes you to the message composition screen
Inbox - takes you to the received message list view
Sent - shows a list of recently sent messages.
To compose a new message, select the type of message from the drop down
menu and the destination. This can be by directly entering the MMSI, or by
selecting from a list of visible targets.
The message text is entered using the on screen keyboard. Messages are
limited to 80 characters in length.
Class B AIS transceivers are permitted to receive broadcast
SRMs and broadcast text messages, however this function is not
mandatory. Some Class B AIS transceivers are not able to
receive addressed SRM or text messages. There is therefore no
guarantee that text messages or SRMs sent by this device to a
Class B AIS transceiver will be received.
4.6.9Long range messages
If the AIS transceiver is connected to a long range communication system via
the long range communications port then long range interrogations may be
received. These are requests for information from a distant base station
beyond normal AIS operation range.
The AIS transceiver can be configured to automatically respond to Long
Range (LR) interrogations, or you can opt to respond to any interrogation
manually. Automatic response is the default setting, but this can be changed
on the ‘Home’ > ‘System settings’ > ‘Advanced’ > ‘Radio and Long range settings’ menu.
When a Long range interrogation is received you will be alerted by an onscreen pop-up message.
In automatic response mode simply review and acknowledge the notification
screen using ‘Acknowledge’. In manual response mode you should review the
request and select either the ‘Respond’ or ‘Decline’ option as appropriate.

4.11.2 Target filtering
From the ‘Target list’ options menu, if 'Show Filter Settings' is selected, a
screen is displayed indicating which filter parameters can be set to reduce the
amount of data displayed on screen. This screen can also be accessed
through ‘Home’ > ‘System settings’ > ‘User settings’.
Filters can be toggled on and off on the ‘Target list’ by pressing the
‘Options menu’ key and selecting ‘Toggle Filters On / Off’. The
bottom line of the ‘Target list’ shows how many targets are visible or
filtered out. If a filter is set, the filter icon is displayed at the top of the
screen.
The Filters icon does not represent CPA/TCPA settings.
4.11.3 CPA/TCPA Settings
The AIS transceiver can be configured to identify approaching vessels which
fall within certain limits. The Closest Point of Approach (CPA) defines a
boundary around the own vessel upon which, if breached, will trigger an alert.
Time to Closest Point of Approach (TCPA) can only be set if CPA is set, and
will trigger the alert if the time to the CPA limit is breached.
These parameters are set on the ‘Home’ > ‘System settings’ > ‘User settings’ > ‘Filtering and CPA/TCPA Settings’ menu.
The target list shows targets which trigger the CPA/TCPA alert in red.
Page 56
Operation
These CPA/TCPA figures are calculated solely on AIS data and should not be
used for anti-collision purposes.
Note: Setting the CPA/TCPA filter will not activate the Filters Icon.
4.11.4 Target plot
The ‘Target plot’ screen shows the location of other AIS equipped vessels and
shore stations relative to your own vessel. The ‘Target plot’ screen provides a
basic overview of AIS targets and should not be regarded as a substitute for
display of AIS information on a dedicated electronic chart display system
(ECDIS).
The plot range can be adjusted by rotating the scroll wheel which cycles
through the ranges 0.1NM up to 100NM. The range relates to the radius of the
outer range ring shown on the screen.
Individual targets can be selected by using the arrow keys. When selected a
square outline will appear around the target and the vessel details will be
shown on the left hand side of the screen.
By pressing the options menu key, additional display features can be selected.
If the Own Vessel Details option is selected the left hand side of the screen will
change to show own vessel dynamic data.
If the MOB Details Display option is selected, the target plot will change to
show only AIS-MOB, AIS-SART, and AIS-EPIRB devices. The left hand side
of the screen will show the range and relative bearing to whichever target is
currently highlighted using the arrow keys.
4.12 Micro SD card data input
On the front of the AIS transceiver under the cover on the lower left hand side
is a socket for a Micro SD memory card. See Figure 25. This can be used to
upgrade the unit firmware, display detailed charts or to log port data. Note the
orientation of the Micro SD card, which is critical to ensure the product is not
damaged.

4.12.1 Loading new charts
The AIS transceiver always contains a basic low resolution world chart.
More detailed resolution charts can be purchased and overlaid onto the AIS
transceiver’s chart display.
The AIS transceiver will read only Jeppesen C-MAP MAX format Micro SD
cards. See your dealer for available charts for your region.
Insert a C-MAP Micro SD card into the Micro SD card socket. The AIS
transceiver will then automatically overlay that higher resolution chart region
onto the relevant region on the AIS transceiver’s world chart.
Remove the Micro SD card and the region will revert back to the basic world
chart.
Page 58
Operation
4.12.2 Upgrading the unit firmware
If a Micro SD card that contains valid upgrade firmware is inserted into the card
socket, the unit will recognize the new firmware and will display a message
asking you if you want to install it. The system will guide you to the appropriate
menu screen, where the firmware update can be applied.
4.12.3 Logging ports to the Micro SD card
If a Micro SD card is inserted into the card socket, the AIS transceiver can be
configured to output specific data to the card. This is accessed from the
individual port menu (from the ‘Home’ > ‘System settings’ > ‘Interfaces’ menu.)
If the ‘Log port to SD’ option is set to ‘On’, data will be output from that port to
the Micro SD card, if one is inserted into the card socket. Only one port can be
logged to the Micro SD card at a time. It is also possible to save a copy of the
current screen to the Micro SD Card for diagnostics purposes by pressing and
holding the rotary controller for at least 3 seconds.
4.12.4 Saving / Loading settings
From the ‘Home’ > ‘System Settings’ > ‘Advanced’ > ‘Save / Restore & Reset
settings’ menu, all system settings and AIS transceiver configuration data can
be saved to the Micro SD card, if one is inserted into the card socket. Settings
previously saved can be restored, thus restoring the AIS transceiver to a
previous configuration. ‘Reset all settings’ will restore the unit to its factory
defaults and is protected by the unit password.
4.13 WiFi Feature
The AIS transceiver provides features to operate with vessel WiFi networks,
or to create its own network. Access the WiFi menu through ‘Home’ > ‘System
settings’ > ‘Interfaces’ > ‘WiFi’.
4.13.1 Client mode
If client mode is selected, the AIS transceiver will search for available WiFi
networks to connect to. If one is selected a password may be required, and
upon connection the details of the connection will be shown in the bottom right
corner of the screen. Once a WiFi connection is made, the AIS transceiver will

The AIS transceiver automatically assigns a priority scheme to connected
sensors. Data from the highest priority sensor will always be used. Sensor
input priority is for:
●Position
● COG+SOG
Page 73
Technical information
● Heading
● Rate of Turn
The sensor input ports have a priority order as shown in Table 10.

Table 10 Port priority order
6.11.1 Position priority scheme
Position information is taken from the highest priority source reporting DTM
with WGS84 or datum override and RMC. If no RMC sentences are available,
position shall be taken from the highest priority source reporting DTM with
WGS84 or datum override and any one of:
●GGA
●GNS
●GLL
The following sentences are only processed if they are from the currently
selected position source:
●RMC
●GGA
●GNS
●GLL
Page 74
Technical information
●GBS
●GRS
●GSA
●GSV
●GFA
When no position has been received on the selected port for 30 seconds, the
port is deselected as a position source, and a new source selected as
described above.
6.11.2 Course and Speed priority scheme
COG and SOG are taken from the highest priority source reporting any one of:
● RMC (with DTM=WGS84 or datum override)
●VTG
● VBW
VTG and VBW are only processed if they are from the currently selected COG
& SOG source. When no COG+SOG has been received on the selected port
for 30 seconds, the port shall be deselected as a COG+SOG source, and a
new source selected as described above.
6.11.3 Heading priority scheme
Heading shall be taken from the highest priority sensor reporting any one of:
●HDT
●THS
HDT and THS are only processed if they are from the currently selected
Heading source. When no heading has been received on the selected port for
30 seconds, the port shall be deselected as a heading source, and a new
source selected as described above
Page 75
Technical information
6.11.4 Rate of Turn priority scheme
Rate of Turn shall be taken from the highest priority sensor reporting ROT.
ROT shall only be processed if they are from the currently selected Rate of
Turn source. When no Rate of Turn has been received on the selected port for
30 seconds, the port shall be deselected as a Rate of Turn source, and a new
source selected as described above.
6.12 Compatibility mode
Some devices require the use of Compatibility mode for correct operation.
When operating in the standard mode the fix quality flag indicates the type of
GNSS position that is being reported. In compatibility mode, the fix quality
reported will either be No GNSS or GNSS.
On the ‘Home’ > ‘System settings’ > ‘Interfaces’ screen, under the
configuration menu for each sensor port there is an On / Off toggle which can
be set if Compatibility mode is required for that port.
6.13 Message 24 content
The Unit Serial Number transmitted in AIS Message 24B, in response to a
Message 15 request, is encoded as follows (note that these characters
represent individual bits in the data):
wwww wwyy yxxx xxxx xxxx
w = week (0 - 52)
y = years since 2014 (0 - 7)
x = incrementing number (0 - 2047)

or High VSWR.
● Some older AIS devices and chart
plotters do not process the specific
class B message which provides the
vessel name (message 24). This is
not a fault of your AIS transceiver.
Software upgrades are available for
many older chart plotters which will
correct this issue. The other vessel
should update its AIS unit and / or
chart plotting software to receive AIS
message 24.
● Check Compatibility Mode option in
the Interface Settings Menu.
● Check the Baud Rate set.
● Check the wiring is correct.
● Ensure VHF Antenna is as far away
as possible from metallic structures
and any other antennae.
● Ensure VHF Antenna is as high as
possible.
● Ensure VHF Antenna is suitable for
AIS i.e. 3dBi Gain, 156-162MHz, and
uses high quality RG213 or RG214
cable.
● The VHF Antenna cable should be as
short as possible and no more than 30
metres (100ft) in length.
